NECK-YOKE SWIVEL.

SPECIFICATION forming part of Letters Patent No. 368,381, dated August16, 1887.

Application filed November 12. 1886. Serial No. 218,701.

To all whom it may concern.-

Be it known that I, JAMES Mon'roN COLMAN, of New Castle, in the countyof King and Territory of WVashington, have invented a Neclc Yoke Swivel,of which the following is afull, clear, and exact description.

This invention relates to a simple, cheap, and durable neck-yokeattachment, and one wherein the parts are so adjusted as to permit auniversal action, whereby it will be found that the device constitutes athoroughly satisfactory and efficient attachment when applied, as willbe hereinafter described.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of my form of neck-yoke swivel, the partsbeing repre sented as they appear when arranged in connection with aneck-yoke and pole. Figs. 2, 3, and 4 are detailed views representingseveral of the parts employed to form the swivel illustrated in Fig. 1.

In the drawings, represents the pole ofa vehicle, and 11 the neck-yoke.This neckyoke 11 is encircled by two bands, 12, the ends of which arebolted or riveted to the wings 13 of a block, 14.

A strap or leather, 16, which, as usual, is formed with an aperture, 17through which the pole 10 passes, is held by a cross-bolt, 18, that issupported by a U shaped iron, 19, the lower ends of the arms 20 of saidiron being rounded, as clearly shown in Fig. 4.

The iron 19 carries a short vertical post, 21 the upper end of which isthreaded, as shown (No model.)

at 22. This post 21 passes through a central aperture, 24, that isformed in the block 14, the threaded end of the post being engaged by anut, 2, above which there is arranged ajamnut, 3. i

From the construction described it will be seen that the neck-yoke maybe turned in an ydireetion in a horizontal plane upon the post orstandard 21, and that it may be swung as desired in a vertical plane byturning it upon its connection with the pole of the vehicle, whereby Iobtain a perfectly free and easy motion for the horses, the advantage ofwhich will be readily appreciated by those who have been troubled withthe old form of neck-yoke clip.

Having thus fully described my invention, I'claiin as new and desire tosecure by Letters Patent- A neck -yoke swivel comprising the U shapediron 19, having apertures in its depending ends 20, and a vertical post,21, having threads 22, the leather 16, having a cross-bolt passedthrough it and secured in the apertured ends 20, the block 14, having acentral vertical aperture, 24, receiving the post 21, and wings 13,apertured at right angles to the vertical aperture 24, the nuts 2 3, andthe neck-yoke bands 12, bent parallel at their ends to receive the cars13, said bent portions having apertures in alignment with those of theears 13, and passed therethrough, substantially as set forth.

JAMES MORTON OOLMAN.
